- Both passive and active immunity can be either naturally or artificially acquired. In this section we will look at artificially acquired immunity. a. Active artificially acquired immunity (def) Active artificially acquired immunity refers to any immunization with an antigen.2. During artificially acquired active immunity, one is immunized with one or more of the following: attenuated microbes, killed organisms, fragmented microorganisms, or antigens produced by recombinant DNA technology, or toxoids.ith artificially acquired active immunity, one is immunized with one or more of the following: 1. Attenuated microbes (see Fig. 1) Attenuated microbes (def) are living, non-virulent strains of a microbe.

Acquired Immune System (B Cells and T Cells) Lymphocytes are a type of white blood cell. There are two types of lymphocytes of the acquired immune system: T cells and B cells. There is a third type of lymphocyte known as natural killer (NK) cells, but these are a part of the innate immune system. T cells: Mediated immunity. T cells account for about 80% of all lymphocytes.

- Passive immunity occurs when another person or animal develops immunity and the immunity is transferred to a nonimmune individual. Active natural immunity-results when a person is exposed to a harmful antigen, contracts the disease, and recovers.

acquired immunity Naturally acquired immunity is obtained by the development of antibodies resulting from an attack of infectious disease or by the transmission of antibodies from the mother through the placenta to the fetus or to the infant through colostrum and breast milk.

- There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used. Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacteria in a laboratory.ive attenuated vaccines. Live vaccines are derived from “wild,” or disease-causing, virus or bacteria. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. For example, the measles vaccine used today was isolated from a child with measles disease in 1954.

Immunity (medical) Artificially acquired passive immunity is a short-term immunization induced by the transfer of antibodies, which can be administered in several forms; as human or animal blood plasma, as pooled human immunoglobulin for intravenous (IVIG) or intramuscular (IG) use, and in the form of monoclonal antibodies (MAb).rtificially acquired active immunity can be induced by a vaccine, a substance that contains antigen. A vaccine stimulates a primary response against the antigen without causing symptoms of the disease.

The Lymphatic and Immune Systems Active immunity: The production of antibodies against a specific agent by the immune system. Active immunity can be acquired in two ways: by contracting an infectious disease -- such as, for example, chickenpox; or by receiving a vaccination usually pe-- such as, for example, against polio.

- Active and Passive Immunity. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. Artificially acquired active immunity can be induced by a vaccine, a substance that contains the antigen.

An example of immunity to a principle other than infection is the immunity that develops after grafting tissue, or so-called transplantation immunity, in which immune lymphocytes are the main factor.Mechanisms of immunity.ctive and Passive Immunity.

- Naturally acquired passive immunity occurs when maternal antibodies cross the placenta during gestation, or are passed on to a newborn via the mother's breast milk. Immunoglobulin G (IgG) is the only antibody able to cross the placenta to the fetus. IgG is the most abundant antibody in the human body, representing about 75%–80% of all antibodies. It protects the fetus against infection during gestation and the neonate immediately after birth.

Vaccine Immunity Vaccine Immunity. By Dr Ananya Mandal, MD. The immune system of the body functions to protect it against invasion by germs and microbes. When an individual is vaccinated against a disease or an infection, his or her immune system is prepared to fight the infection.his type of immunity against an illness is called naturally acquired immunity. In addition, if the disease is contagious it may also be passed on to family members, friends, or others who come into contact. Vaccines, which provide artificially acquired immunity, are a much safer way to become immune.

Immunity (medical) This type of immunity is natural because it is not induced by deliberate exposure. Many disorders of immune system function can affect the formation of active immunity such as immunodeficiency (both acquired and congenital forms) and immunosuppression. Artificially acquired

Immunity Types Exposure to the disease organism can occur through infection with the actual disease (resulting in natural immunity), or introduction of a killed or weakened form of the disease organism through vaccination (vaccine-induced immunity).assive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. A newborn baby acquires passive immunity from its mother through the placenta.

Passive immunity Passive immunity is the transfer of active humoral immunity in the form of ready-made antibodies from one individual to another. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases.

About Lymphocytes and Phagocytes...? Immunity Humans have three types of immunity — innate, adaptive, and passive: Innate Immunity Everyone is born with innate (or natural) immunity, a type of general protection.Many of the germs that affect other species don't harm us.For example, the viruses that cause leukemia in cats or distemper in dogs don't affect humans. Innate immunity works both ways because some viruses that make humans ill — such as the virus that causes HIV/AIDS — don't make cats or dogs sick.nnate immunity also includes the external barriers of the body, like the skin and mucous. membranes (like those that line the nose, throat, and gastrointestinal tract), which are the. first line of defense in preventing diseases from entering the body.
